This will not be a complete answer as I believe we will have to correct a few things and check again before we reach the solution.

First, we notice that you have a Broadcom wireless driver installed. Your device is a Realtek. Let's remove the incorrect driver:

sudo apt purge bcmwl-kernel-source

Second, we notice that both Wicd and Network Manager are installed. New in Ubuntu 17.10 and later is networkd and netplan. Netplan clearly says NM is in charge. From your readings:

[/etc/netplan/01-network-manager-all.yaml]
network:
  version: 2
  renderer: NetworkManager

I recommend that you remove Wicd:

sudo apt purge wicd*

After doing so, tell us if this line remains in NetworkManager.conf

cat /etc/NetworkManager/NetworkManager.conf

Does this line remain after removing Wicd?

[keyfile]
unmanaged-devices=interface-name:wlo1

If it remains, we will need to edit the file to remove it.

Once these steps are taken, reboot and report back your result and we'll continue if needed.

EDIT: Please remove the keyfile section; from the terminal:

sudo nano /etc/NetworkManager/NetworkManager.conf

Remove this section completely:

[keyfile]
unmanaged-devices=interface-name:wlo1

Save (Ctrl+o followed by Enter) and close (Ctrl+x) the text editor.

Restart NM:

sudo service network-manager restart

It might take a reboot. Any improvement?
